He won the Copley Medal in 1826 and the Gold Medal of the Royal Astronomical Society in that same year. He was knighted by King William IV in 1831. Starting around 1826, James South made plans for a new, larger telescope, an equatorially mounted achromatic refractor (a telescope with a lens) in a new observatory. He bought a 12-inch (actually about 11.8) aperture lens from Robert-Aglaé Cauchoix in Paris for about 1000 pounds, large enough to be the biggest achromatic object lens in the world at the time.

It is often questioned if the word- learning constraints are specific to the domain of language, or if they apply to other cognitive domains. As for the whole object assumption, evidence suggests that the idea of objects is more advantaged than characteristics or relations. Children assume a label refers to a whole object because the object is more salient than its properties. The whole object assumption may reflect non-linguistic levels of an object and exploits the cognitive tendency to analyze the world through a whole object lens, meaning the whole object assumption can be applied to cognitive domains outside of language.

Heliometer at the Kuffner observatory (Vienna, Austria) A heliometer (from Greek ἥλιος hḗlios "sun" and measure) is an instrument originally designed for measuring the variation of the sun's diameter at different seasons of the year, but applied now to the modern form of the instrument which is capable of much wider use. The basic concept is to introduce a split element into a telescope's optical path so as to produce a double image. If one element is moved using a screw micrometer, precise angle measurements can be made. The simplest arrangement is to split the object lens in half, with one half fixed and the other attached to the micrometer screw and slid along the cut diameter.
